the purpose is to provide signal to an amplifier and then programm decoder to break down coded type signals. you might not hear anything as the level is way too low for a speaker load of only 4 or 8 ohms.
hook input to an amp or directly to your computer to test.

questions to answer.. what does the display show if put on 146.520.. is it 146.525 ??? is the +5 offset switch/setup turned on?? How do you know it transmits correctly. be sure and look at the display when transmitting. Everything is worth fixing.. Narrow down the fault as accurate as you can. Then ...

If you chart out the lengths you will see some multiples of length. 40 and 15 are related.. as are 10 and 20 or 40 and 80. Simpler antenna would be a fan dipole. one feed point, multiple wires cut to length.. Plus a lot of weight for that many traps.. Think separate antennas. An 40/80 trap dipole,(b...

not familiar with either device. but........ it must be DC and there for 2 wires.. plus and minus.. possibly a third wire which would be frame ground for safety.. figure out the plus side of the panel and plus side of input to controller. wire that and then the other should be minus. if a third wire...

That is the equipment you intend to use. I still dont understand the question or concerns..
That kind of equipment is pretty generic.. Why would Tennessee be any different.?

I dont live there but amateur radio is OK every where.. more or less.
Just what are your concerns.. mountains,, local laws/zoning.. interference,man made or atmospheric??
be Pacific.........................................

I would guess electrical grease from electric supply/hardware store, used on aluminum wire connections,, also in auto work.. My suggestion is just rub some on your fingers to make them slightly slick and wipe along the shaft. thus a very thin coat. At a slow speed, not much lub is needed.

Any mars mod should be available from your Mars co-ordinator.. Also,,if Mars uses vhf uhf...
Any other,, suggests use in un-authorized frequencys and is probably why you have had no replys , as most hams will not assist in messing up a prefectly good radio.

forgot.. state your location so any local maybe able to help out and also advise on ham fests in the area

a local ham fest is a good bet.. also if remote to anywhere, QRZ.COM sale forum. also here on QTH... Eham.net. lastly Craigs list.. be careful of the "" I'll give you a hunnert bucks to take it off your hands::"" people.. Look thru the QRZ sales stuff to try and get a ballpark price on the stuff. re...

I didnt check , but if its really a WRL amp then its 30 plus years old. Could be a lot more than weak tubes in it..

no one else answered...6/25

first off, compare the mic wireing of the 7000 with the 7200 to be sure they are either the same ,
or if different, which wires.
the if necessary, open up the heil mic and wring out the wireing with your ohm meter.
Basic door bell electricity..

you can not just swap mics with out verifying the pin out of the connectors. Especially since electret mics have an 8 volt or so line to power the element. Connecting the wrong pin to the 8 volts would either wipe out the 8 volt supply or put 8 volts somewhere you really dont want it.. Get help with...

the displays have very tiny contacts.. smaller than a pencil line..and close together. if the display gets just a bit twisted or slid sideways the contact will be lost. I would eye ball the display very closely,if your lucky go by the dust rilng around it to see if its moved. I had trouble replacein...

First problem.. get out ;your ohm meter hand ring out the power switch and or wireing to it. That should find the 'turn off' problem.. You didnt mention if you had to 'turn on the switch' after unplugging to get it to power back up..... that could make a difference as to how to troubleshoot. Also to...

I don't believe that BS about NSA recording everything. With all the calls and computer users and cell phones in the US it would take a disk farm the size of Connecticut to store it all. And a population the size of Maine to do any searches of what might be of value to some one. And over 90% of the ...

the antenna would be only 1/20th of the proper length on 40 meters. a quarter wave on 2 meters is about 19 inches.
a quarter wave on 40 meters about 10 feet. I dont think you could get any tuner to work with that difference.

60 feet of pipe will be rather heavy as an addition for the rotor to turn..
plus you would have to slide the pipe into the tower and then push it up and add another piece..
easier if the tower was put up with the pipe inside already..

I'll bite.. what is a ''radio detector' .???? i know of diode detectors and product detectors,slope detectors (for FM)..
be more specific..

first off is it a dipole configuration?? If so ...do the dipole calculation for the center freq you want to use..(17 is fairly narrow band so it should work all over the band. )) adjust the wire length accurately.. inches count.. also direction.. I find most activity with an antenna northwest/southe...

I would look in the $500 range.. ICOM 706markII is a nice small foot print rig. 12 volt. HF and 2 meters and 440. go to 'rigpix' and scan thru some pictures of ICOM kenwood and yeasu and even Alinco for small rigs. also peruse the eh-ham reviews.. for rigs of the past 15 years or so.. 10 to 15 year ...

maybe slightly as there is now less meatal around it but it should be not an issue..

Just try it.. set it in a wooden step ladder and test it out..
or hanng from some trees with string to test..

How do you know they are ""needed"... if they are known then there should be some connection to where the instructions are located to accomplish them.. no one has answered so maybe there are not any really ""needed" mods. Just some one thinking they are smarter than the engineers that built it.

for the mics you can ring out the wireing. open the mic up and the cover on the connector. draw the conector pins and the wire colors. do the same at the other end. mic should have two or maybe 3 wires. if three its likely the capacitor type that needs voltage to run. they are also polarity sensitiv...

With the present sun spot cycle on the down swing.. ten and twelve will be the first to go dead. so if ;you are going cheeeeep look to 20,40, 80 bands.. a WARC band radio will be newer, although m y FT980 I bought to get the WARC bands..its 25 years old. I really like 17 meters... Kenwood TS 520/530...
